Copper Pipe & Fittings

Copper Pipe & Fittings deliver reliable, long-lasting plumbing performance for potable water, HVAC, and hydronic heating. Copper tubing resists corrosion, tolerates high temperatures and pressures, and has natural antimicrobial properties—ideal for kitchens, bathrooms, boiler loops, and refrigerant lines. It’s widely code-approved, recyclable, and quiet in service, reducing water hammer and vibration.

Choose the right copper pipe type for your job: Type K (thick wall) for underground and high-pressure runs, Type L for interior hot and cold water distribution, Type M for low-pressure residential lines, and DWV for drain, waste, and vent systems. Available in rigid (hard-drawn) straight lengths and soft (annealed) coils, common sizes include 1/2-inch, 3/4-inch, and 1-inch, with larger diameters for main trunks and mechanical applications.

Match pipe with quality copper fittings to route, adapt, and terminate lines. Stock elbows (45° and 90°), tees, wyes, couplings, slip couplings, unions, reducers, caps, stub-outs, and male/female adapters. Connection options include sweat/solder, brazed, press-fit (V, M, or XL profiles), compression, flare, and push-to-connect. Use lead-free, dezincification-resistant brass where required, and dielectric unions when transitioning to steel to prevent galvanic corrosion.

Build faster, cleaner, and leak-free with the right tools and practices:
- Tubing cutter and fine reamer/deburring tool for clean, square ends
- Tube bender for soft copper to protect the ID and flow
- Flux, lead-free solder, and an adjustable torch or fire-safe press tool
- Cleaning pads/brushes to prep fittings and tubing to bright metal
- Heat evenly, pull solder by capillary action, and allow natural cooling
- Support runs with copper-compatible hangers and maintain expansion gaps
- Pressure-test, then insulate hot and cold lines to cut heat loss and condensation
